We study the influence of temperature of a working medium and loading frequency on the contact fatigue of 20KhN3A and ShKh15 steels in oil and in a 3% NaCl aqueous solution. It is shown that, as the loading frequency increases, the contact fatigue of

We investigate the influence of prehydrogenation from the gas phase on high-temperature (230–240°C) corrosion-fatigue strength of titanium PT-7M, PT-3V, and 27 alloys and of their welded joints in solutions of chlorides, alkalies, and in distilled
